Duncan, 28, was secretly married when she met and fell for Tollefson, 27, on Survivor: South Pacific in the summer of 2011 but now the tribemates are headed down the aisle.

"He did good," Duncan wrote on Facebook along with a photo of her sparkling engagement ring of interlocking circles in a complex pattern.

The "Skinny Dippin' " singer portrayed herself as single on the 23rd season of the CBS reality show, but she had actually been married to Donny Fallgatter, lead singer for the band KingBilly, since August 2010.

Fallgatter and Duncan had kept their marriage a secret from even friends and family until Duncan confessed her feelings for Tollefson to Fallgatter during a phone call made just before she returned from filming Survivor, a source close to the couple told PEOPLE in 2011.

The country couple's divorce proceedings were complete in November 2011 and now Duncan and Tollefson – a self-described environmentalist – are happily celebrating their impending nuptials.

"Thanks to everyone for the best wishes on mine and @whitneyduncan's engagement," Tollefson tweeted. "I know real original proposing on Valentines day ha."
